This 2-7/8 EUE pin x 3-1/2 EUE box pup joint, measuring 180mm in length, is a threaded connector used to join tubing strings of different nominal sizes in oil and gas wells.

Frequently Asked Questions About 2-7/8 Eue Pin X 3-1/2 Eue Box 180mm from Henan Dongfanglong Machine Manufacture Co., Ltd
A pup joint with a 2-7/8 inch pin and a 3-1/2 inch box is used as a crossover or saver sub.

Sourcing 2-7/8 Eue Pin X 3-1/2 Eue Box 180mm from Henan Dongfanglong Machine Manufacture Co., Ltd - China Import Guide

When sourcing this 2-7/8 x 3-1/2 EUE pup joint from Henan Dongfanglong, your first step is to confirm all technical specifications against your well schematic or equipment list. Verify the exact material grade required, the thread dimensions and gauging standards, and the 180mm length tolerance. Requesting a detailed datasheet or drawing from the supplier is advisable.

Clarify all commercial and logistics terms before placing a purchase order. Key items include the Incoterms (e.g., FOB Tianjin or CIF your port), the total landed cost, the payment terms (e.g., T/T, L/C), and the estimated shipping date. For fittings, sea freight in cartons on pallets within a container is typical. Ensure the packaging protects the threaded ends from damage during transit.

Establish a quality assurance protocol. Beyond relying on the supplier's API certification, consider specifying third-party inspection at the mill or prior to shipment. This inspection can include dimensional checks, visual examination for defects, and review of the material test reports. Having clear acceptance criteria in your purchase order protects your investment and ensures the components will perform as expected downhole.
